I think time as we know it - As a dimension, is broken. Purposefully broken.
And without being able to see the whole dimension, we also cannot see any further dimensions beyond it.
That means, however, that moving either forward or backward through time is also necessarily broken. We are caught, only in the now.
The rolling back of the sky, as mentioned in Biblical end times events, I believe, is the repair of time, and the immediate comprehension of everything that exists.
